To aZZ whom it may concern.-

Be it known that I, J OSEPII V. KAPP, a citizen of the United States, residing at Newark, in the county of Essex and State of New J ersey, have invented certain new and useful Improvements in BenchPins; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The present invention has reference to improvements in bench-pins, for use in toolmakers, jewelers, and similar arts; and the invention has reference, more particularly, to a novel construction of bench-pin which is universal in its action thereby providing a table upon which the work to be operated upon can be held, the said table being capable of adjustment in any desired angle or plane.

The present invention, therefore, has for its principal objects to provide a simple, inexpensive, and efficient construction of bench-pin, the table of which may be secured with its plane at any desired angle of rotation about a horizontal axis; and a further object of the present invention is to provide a bench-pin which may be readily and quickly attached to or detached from the work-bench or table of the artisan, and which by reason of the varied adjustment of position of wlrich it is capable, affords a most convenient place upon which to hold or secure a die, tool, piece of jewelry, or the like, which the artisan is working upon or making; and, furthermore, the present invention provides a bench-pin which may be used with economy of time and a saving of labor in doing a variety of work where a bench-pin is serviceable.

The invention consists, primarily, in the novel construction of benchp.in hereinafter more fully set forth, as well as in the various novel arrangements and combinations of the parts thereof, all of which will be more par ticularly described in the following specification, and then finally embodied in the clauses of the claims, which are appended to and which form an essential part of this specification.

The invention is clearly illustrated in the accompanying drawings, in which I-- Figure 1 is a side elevation of the benchpin embodying the principles of the present invention, the said bench-pin being illus trated in its operative relation with a work bench or table, the said work-bench or table being indicated by dotted lines. Fig. 2 is a front elevation of the same, the workbench or table being indicated by dotted lines.

Fig. 5 is a top or plan View of a modified form of table for a benchpin embodying the principles of the present invention, being constructed in such form that a covering or sheath of wood or similar material may be secured thereto. Fig. 6 is a top or plan view of said modified form of table for bench-pin illustrated in Fig. 5, the covering or sheath of wood or similar material beingsecured thereto. Fig. 7 is avertieal cross-section of the same, taken on line 7 7 in said Fig. 6, looking in the direction of the arrow X. Fig. 8 is a side elevation of another modified form of table for bench-pin embodying the principles of the present invention. Fig. 9 is a back view of the same; and Fig. 10 is a central vertical section of the same.

Similar characters ofreference are employed in all of the said hereinabove described views to indicate corresponding parts.

Referring now to the several figures of the drawings, the reference-character 1 indicates the complete construction of the bench-pin, comprising a clamp-bracket 2, provided at its lower end with a right-angled extension 3 upon the end of which is formed integrally with the said extension 3, a screw-threaded nut 4, the said screw-threaded nut being adapted to receive the clamp-screw 5, and said clamp screw 5 being provided at the lower end with a winged linger-piece 6 secured to the said clamp-screw by means of a pin 7. The upper end of the said clampscrew 5 is provided with a ratchet-toothed head 8 connected thereto in such a manner IIO ear 11 provided at its outer end with a perforated disc 12. Pivotally connected to the said lug or ear 11 of the clamp-bracket 2 is a receiving socket 13 which is provided with an outwardly extending lug or ear 14 having upon its outer end a perforated disc 15. The said perforated disc 15 is held. in pivotal relation with said perforated disc 12 of the lug or ear 11 upon the clamp-bracket 2, by means of a screw-threaded bolt 16 provided at one end with a head 17 and at the other with a winged nut 18, thus permitting the adjustment of the receiving-socket 13 to any desired angle in a vertical plane, as will readily be understood from an inspection of the accompanying drawings. The said receiving-socket 13 is split through one side, forming a longitudinal opening 19 and, the said receiving socket 13 is further provided with a pair of cars or lugs 20 and 21 respectively one on either side of the lon itudinal opening 19, the said ear or lug 20 being provided with a perforation or hole 22, and the said ear or lug 21 being provided with a screw-threaded opening or hole 23. A bolt provided with a screw threaded shank 24 and a head 25 passes through the perforation or hole 22 in the said lug or ear 20, and screws into the screw-threaded opening or hole 23, serving to draw the two halves of the receiving-socket 13 together and thereby lock or hold a shaft or rod 26 which rides within the receiving socket 13, in any desirable position, by means of the friction between the inner sides of the receiving-socket 13 and the surface of the said shaft or red 26. The head 25 of the bolt is provided with holes or openings 27 adapted to receive a pin or other tool to facilitate the turning the said bolt to tighten up the receiving-socket 13 for the purpose above mentioned.

The shaft or red 26 is provided upon its upper end with a perforated disc 28 and pivotally secured to the said perforated disc 28,'

so as to be capable of a lateral movement, is the table 29 provided upon its rear portion with a downwardly extending lug or flange 30 said lug or flange being provided with a hole or opening 31 and being adapted to be brought in pivotally connected engagement with the said perforated disc 28 of the said shaft or rod 26, by means of a bolt comprising a screw-threaded shank 32 and a head 33, said screw-threaded shank 32 of said bolt extending through the perforation of the disc 28 and the hole or opening 31 of the lug or flange 30, and a Winged nut 34 on said screwthreaded shank 32 being adapted to lock the s aid lug or flange 30 and the perforated disc 28 in any desired position, thereby providing an adjustment of the said table 29 with its plane at any angle of rotation about a hori- I zontal axis, as will be readily understood from an inspection of the drawings. The said table 29 is further provided at each side thereof, and extending along the bottoln or under side, with a pair of ribs 35 adapted to give strength to the said table 29, and the table 29 is further provided at its free end with a wedge-shaped opening 36 through which the artisan may insert the instrument or tool, such as afile or the like,while operat ing upon the piece of work held orstrapped upon the said table 29.

The shaft or red 26 is provided with a split collar 37 slidably arranged thereon and adapted to be set or tightened on the said shaft orrod 26, to mark the position to which the said shaft is to be raised or lowered, before the receiving socket 13 is tightened on the shaft or red 26.

Referring now more particularly to Figs. 5 and 6 of the drawings, there is shown a slightly modified. construction of table 38 for the bench-pin 1, the said table 38 being provided with a pair of longitudinally extending wedge-shaped ribs 39 and screw-holes 40 upon which is arranged a facing or sheathing of wood 41, or other suitable material, secured to the said table 38 by means of the screws 42, this said facing or sheathing of wood 41 providing a soft surface upon which fine work may be held with a minimum danger of scratching, abrading or otherwise injuring the same.

Referring now more particularly to Figs.

'8, 9 and 10 of the drawings, there is shown a further modification of table for a bench-pin 1 comprising a table-block 43 made preferably of wood or similar material, said tableblock 43 being provided with a rear-wardly extending tongue 44, and said tongue 44 be: .ng adapted to be inserted. in a receivingsocket or yoke 45 which is split through the upper side thereof to form an opening 46. The said receiving-socket or yoke 45 is further provided with a pair of ears or lugs 47 and 48, respectively, one on either side of the said opening 46, the said ear or lug 47 being provided with a perforation or hole 49 and the said ear or lug 48 being provided with a screw-threaded opening or hole 50. A bolt provided with a screw-threaded shank 51 and a head 52 passes through the said perforation or hole 44 in the said ear or lug 47 and screws into the said screw threaded opening or hole 50, serving to draw the two halves of the receiving socket or yoke 45 together and thereby lock or hold the said rearwardly extending tongue 44 of the table block 43 therein. The head 52 of the bolt is provided with holes or openings 53 in which may be inserted a pin or other tool adapted to facilitate the tightening up of the same. The said securing socket or yoke 45 is furtherrnore provided with a downwardly extending lug 54 formed with a hole or perforation 55, and the said lug is adapted to be brought in pivotal connection with the perforated disc 28 of the said shaft or rod 26 in the same manner and by the same means previously described.

From the foregoing description and the accompanying drawings it will be readily understoodthat I have provided a novel construction of a bench-pin that is universal in its action, that is, that the table thereof may be secured with its plane at any angle of ro tation about a horizontal axis, thereby providing a very convenient rest upon which to hold the delicate work and hence greatly aiding the artisan in the execution of that work.
